Description Dipta Biswas 2020-08-08 15:16:58 UTC
SUMMARY: kdeinit 5 crashes when I open dolphin. No previous solution in this forum works.


STEPS TO REPRODUCE
1. Close dolphin, if it's already open
2. Open dolphin

OBSERVED RESULT: kdeinit crashes


EXPECTED RESULT: shouldn't crash


SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: 20.04; 5.18 probably
(available in About System)
KDE Plasma Version: 5.18 probably
KDE Frameworks Version: Idk but latest one probably, installed kubuntu-desktop on top of ubuntu last month
Qt Version: Idk but 5.something

ADDITIONAL INFORMATION
I'm not a pro coder and I've never reported bugs before, so sorry if I'm vague. :) I can't find kdeinit 5 in products list so I reported it as dolphin bug. But I know it's not a dolphin bug.

Application: kdeinit5 (kdeinit5), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 1 Nate Graham 2020-08-08 18:29:07 UTC
Thanks for the bug report. Looks like there's something about your tags that Baloo doesn't like:

Would yo be able to provide a list of all the tags you're using in Dolphin? Thanks!
Comment 2 Nate Graham 2020-08-08 18:29:57 UTC
Also could you provide the version of KDE Frameworks that are installed on your machine? You can find this out in the Info Center app.
Comment 3 Dipta Biswas 2020-08-09 09:36:42 UTC
Well, I've never added any tag to any file/directory in dolphin (or any other file manager). I don't know if they're automatically added. 
KDE Frameworks version: 5.68.0
Comment 4 Nate Graham 2020-08-09 13:32:25 UTC
Great, thanks.
Comment 5 Dipta Biswas 2020-08-10 14:28:39 UTC
Update: Now I get it even when I start a Plasma session and also when I start konqueror, from both terminal & gui
